You make it sound like vocals are separate and are an obstacle that sometimes must be overcome to get to the music. I guess if you want to look at music like that, that's your prerogative. But that's not how I look at music, generally speaking. To me, the vocals are part of the song, just as much as the lead instrument(s), rhythm instrument(s), percussion instrument(s), etc. Is it possible in music to like some of what is going on in a song and not other parts? Sure. I can like, for example, the percussion without liking the guitars. Or I can like the keyboards without liking the vocals. But if a major part of the music, such as the lead vocals, is something that I don't enjoy, odds are, I won't enjoy the song as a whole package very much. But it's not an issue of separating the vocals. For example, I don't generally like screams/growls. Sometimes they work, but as a general rule, that's not my thing. That being said, I find myself liking some music that has those styles. Recently, for example, I find myself liking the new Trivium album. They music is pretty good, the clean vocals are pretty good, and the screamy growly stuff I find sometimes works and sometimes doesn't. So, anyway, for what it's worth, that's my take.
